Pet Battles haven't been implemented on the beta yet. It might be a while before it's actually available for testing. But if you're interested in trying out the renaming feature, just right click on the pets in your Pet Journal and give it a go.

I'm guessing that when we 'train' in Pet Battling, we'll get back the Wild Pet Targeting and crosshairs when clicking on an appropriate pet to battle... It's interesting (and a little bit frustrating) to watch it all unfold...

A Pet Battle Trainer is in Goldshire on the beta now. It costs 80 gold to train and you must be at least level 5. Tracking the wild pets currently costs 8 copper and requires at least level 5. (Prices subject to change.)

The camarea just does a swing around zoom.
It appears the catch part isn't working yet, but the battling is.
A few notes:
Not all pets have skills yet. In my current team I only have 1 skill out of a possible 9.

Pets before the patch seem to have been wiped from the journal, but not your toons list of known spells, so to get a pet you either need an alt you hasn't leant the pet yet to learn it (adding it to the account wide journal) or re-transfer over you pet heavy toon.

Catching doesn't seem to work yet, it just knocks them out.

already xfered over my main pet collector, still 0 pets. Re-learning them doesn't seem to work either as i just learned core-hound pup on a toon and it didn't get listed as a collected pet.
